Listing Objects with aws s3 ls
When you want to see what is inside a bucket, give aws s3 ls a bucket name. It lists that bucket's objects.
The syntax is aws s3 ls s3://bucket-name. Add a prefix to look inside a "folder."
Running aws s3 ls s3://my-bucket prints the date, size and key of each object.
A common stumble is thinking S3 has real folders. It doesn't — keys just contain slashes, and the folder appearance is a convenience.
In real work, it is how you confirm a deploy actually uploaded what you expected.
AWS
Try it (type this into the pseudo terminal)
❯ aws s3 ls s3://my-bucket
🧑💻 You can type this command into the AWS pseudo terminal to try it yourself (this page itself has no interactive terminal).
